Leonard Goppelt wrote a gem of a commentary on 1 Peter.  I’ve been studying it as I prepare to exhort on the amazingly redemptively-historical 1 Pet 1:10-12.  Here is a typical quote from Goppelt on the text:

Prophecy enables the Church to understand the Christ-event preached to it as fulfillment, as eschatological salvation, and, therefore, to appropriate proclamation as gospel.

It makes the biblical-theological heart warm, doesn’t it?
